FLOAT-CONTROLLED rAUcET,

Application filed June 2, 1925. Serial No. 34,330.

My invention relates to a float controlled faucet, particularly adapted for retaining the level of milk in supply cans of cream separators at substantially fixed levels, and also adapted for other similar uses.

The objects of my invention are: First,

to provide a faucet having a float for regulating the discharge of liquid from said faucet depending upon the height of the liquid in the receiving receptacle, which float may be easily and quickly removed from said faucet for dischar ing liquid directly into said receptacle and for controlling said flow manually; second, to provide a faucet at the discharge end of which is reciprocally mounted a float member through which the liquid from said faucet is discharged and which maybe easily removed from said faucet; third, to provide a faucet in the spout of which is movably positioned the hollow stem of a float member, through the hollow stem of which the liquid of the tank to which said faucet is connected may be discharged when the level of the liquid in the receiving receptacle is below a certain level, and wherebythe liquid normally flowing through said faucet may be shut ofl when the level of theliquid .in the receiving receptacle is raised beyond a predetermined mark; fourth, to provide as a whole a novelly constructed float controlled faucet, and fifth, to provide afaucet of this class which is very simple and economical of construction, durable, automatic in its action and which will not readily deteriorate or get out of order. "With these and other objects in view, as ill appear hereinafter, my invention consts of certain novel features of construction, combination and arrangement of parts and portions, as will. be hereinafter de scribedin detail and particularly set forth in the appended claims, referencc'being had to the accompanying drawings and'to the characters of reference thereon, which form a part of this application, in which:

Figure 1 is a side elevational viewof my float controlled faucet connected with a sup ply receptacle, shown fragmentarily and in connection with a partially filled liquid receiving receptacle, shown fragmentarily and in section, certain parts and portions of the faucet members and the float member being broken away and in section to facilitate the illustration; Fig. 2 is a fragmentary transerse sectional view thereof, taken through me 22 of Fig. 1; Fig. 3 is a transverse sectional view thereof. taken through line 2 3 of Fig. 1, and Fig. 4 is a side elevational view on a reduced scale of my float controlled faucet in connection with the supply receptacle and receivingreceptacle, as us ..:l in connection with a cream separator. Like characters of reference refer to similar parts and portions throughout the sevral views of the drawings.

My float controlled faucet consists essentially of a faucet'member 1, a plug member 2 rotatably mounted in the extended hollow en arged end thereof, a float member 3/ a retaining and guide pin 4, and a retaining ring 5.

The faucet member '1 is adapted to be secured at its one end to the lower portion of a liquid supply receptacle 6 in any suitable manner; The portion of the faucet member 1 connected with the tank 6 is hollow, the hollow. portion thereof communicating. with the hollow port-ion at the extended end of. said member. The plug member 2 is'provided with a hollow plugportion 2 which is tapered downwardly and seats in a correspondingly shaped recess in the extended enlarged portion of the faucet "member 1. Said plug member is provided with a handie 2 for rotating the same within the faucet member I. Said plug member is' also provided with a downwardly extending shank 2 below the hollowtapered portion thereof. The plug portion 2 and the downwardly extending shank 2 are provided with a continuous axial bore 2 which communicates near its upper end, through a transverse port 2*, with the interior of the faucet member 1, the upper end of the" bore 2 extending preferablya slight distance above the upper portion of the transverse port 2 as shown bestin Fig. 1. lVithin the bore 2 of the plugmember 2 is reciprocallypositioned the upper end of the hollow stem 3? of the float member 3, which float member is provided at its lower end with an annul'arly shaped float portion 3 Said stem 3 is provided with a pin 4 intermediate its ends, which extends outwardly through a slot 2 in the shank portion of the plugmember 2 for guiding said float. Near the lower end of the shank 2 of the plug member 2 is'pro vided an annular groove 2 in which is removably positioned a retaining ring 5, for

retaining the stem 3 of the float member 3 within the shank or spout portion of the plug member.

Thus it will be seen that when the liquid in the receiving receptacle 7, in which the liquid is adapted to'be retained at a certain level, falls below said predetermined level, the float member 3 will drop until the pin engages the retaining ring 5,;in which the upper end of the hollow stem 1 tionedbelow the lower portion of the m verse port 2 in the plug member 2, permitting the liquid invthe tank or receptacle 6 to fiow through the hollow stem 2 into thereceptacle 7, providing the handle :2" as shown or the transverse port 2 oi the plug member 2 registers with the passage in the memberl. As the level of the liquid in the receptacle 7 is raised, the float member 3 is correspondingly raised, gradually shutting off the liquid from the receptacle 6 an '7 the upper end of the hollow stem 3 is shifted upwardly to its limit when the liquid from the receptacle 6 is substantially comletely shut off. It-will be here noted that the liquidtrom the receptacle (3 may be shut of at any time or partially shut oft by to tatingthe plug member 2. The float member 8 may be readily removed trom the plug member 2 by removing the retainin ring and withdrawing the stem ot the float member, thus providing a faucet of substantially ordinary construction.

Though'I have shown and described a particular construction, combination and arrangement of parts and portions, 1 do not wish to be limited to this particular construction, combination and arrangement. but desire to include in the-scope of my invention of the construction, combination and ar rangement substantially asset forth in the appended claims.

Having thus described my invention, what I claim as new and desireto secure by Letters Patent is:

1. In a means of the class described, a hollowifaucet member having a tapered portion at one end, a hollow tapered plug member rotatably mounted in said tapered portion and provided with a port ada ted to register with the passage in said hollow faucet memberand having a right angled extendinghandle on its normally upper end and with a tubular extended portion on its normally lower end, anda floatmeinber provided with a tubular portion extending therethrough, said tubular port-ion being reciprocally mounted in said tubular. extended portion and said plug member for controlling the flow of liquid therefrom.

2. In a means of the class described, a hollow'faueet member having a tapered portion at one end, a hollow tapered plug mem :ber rotatablyzmounted in said tapered portion and provided with a port adapted to register with the passage in said hollow faucet member and having a right angled extending handle on its normally upper end and with a tubular extended portion on its normally lower end, a float member provided with a tubular portion extending therethrough, said tubular portion being reciprocally mounted in said tubular extended portion and said plug member for controlling the flow of liquid therefrom, and means tor readily removably connecting said tubular portion wit-h said tubular extended port'on.

f Q 1 a means of th class described, a hollow uicet member having a tapered portion at one end, a hollow tapered plug member rotatably mounted within said tapered por tion and provided with a port adapted to register with the passage in said hollow faucet member and having an'integral extended tubular portion, and a float member provided with a liquid conducting tube shittaoly mounted within said plug member and said extended tubular portion adapted to register with the inlet port in the plug memher and also to cover said port.

l In a'means of the class described, a hollow taucet member having a tapered portion at one end, a hollowtapered plugmember rotatably mounted within said tapered portion and provided with a port adapted to register with the passage in said hollow ta cet member and having an integral extended tubular portion, and a float member provided with a tubular portion extending therethrough, said tubular portion of the floatmember being reciprocally Tnounted in said extended tubular portion and said plug member for controlling the flow of liquid therefrom.

In testimony whereof, I have hereunto set my hand at Holtville, California, this 25. day

of May, 1925.
